Hello.. I got a new graphics card today the Sapphire HD 6570.. I replaced my old gpu with it (onboard) and I installed the drivers on the disc that came with it, During the middle of the installation my PC froze. I rebooted and Reinstalled the drivers, that time they worked until it asked me to restart my PC. whenever I started it back up it would freeze on the welcome screen.. I rebooted a few times and got the same result, So I took the GPU out of my system and plugged in the onboard graphics.. I re-enabled the onboard GPU and downloaded the latest drivers from AMD's website, deleted the old ones, put my card back in and installed the new drivers with the same problems. I really don't know what to do at this point. Please help if you have any suggestions.
